structural details, will definitely appear from the detailed descriptionappearing hereinafter.

The invention consists in certain novel features in construction and incombinations and arrangements as more fully and particularly set forthand specified here inafter.

Referring to the accompanying draw- 1ngs:

Figure 1, is a vertical section through a spring seat to which myinvention is applied.

Fig. 2, is a detail perspective view.

Fig. 3, is a detail perspective view of a modified construction.

In the spring seats of the general type disclosed in the accompanyingdrawings, a suitable covering of fac ng nniterial or upholstery isprovided which extends over the top and sides of the spring constructionand is customarily fastened to the lower frame thereof in any of anumber of ways. This fastening is accomplished by providing frames ofwood, or the like material. and nailing or tacking the ends of the seatcovering thereto, or, where metal frames are used by various complicatedand other expensive arrangements and constructions which often requirethe use of machinery or special tools in fastening the covering theretoand which in a number of instance necessitate sewing or providing theends of the covering with binding or einforcing members. A prevailingarrangement. in the art, where metal frames and cover fastening meansare used, is the provision of various forms and constructions of teeth,prongs, and the like, which are forced, through the covering materialand bent over thereon or clenched. methods and constructions foraccomplishing' the fastening of upholstery or seat covering material tothe spring construction of spring seats, or other seat constructions,are more or less complicated and expensive and necessitate a number ofoperations to form the completed fastening. The invention embodied in mypresent application,

by the arrangement and construction de-' All of these covering materialto cring material therein and thereto.

the spring construction of spring seats. This binding or locking meansconsists of a member which is formed to receive the The upholstery orseat covering is securely locked in and to this receiving member whichis rigidly fastened to a frame of the spring construction, and in thismanner, the upholstery or seat covering material is tightly maintainedupon and in proper relation with respect to the spring seatconstruction, without the use of tacks, prongs, teeth, or the like, orthe complicated or expensive arrangements and constructions heretoforeused for this purpose.

Referring to the particular example illustrated by the accompanyingdrawings, I show a spring construction consisting of the frames 1 and 2,and a series of sprial springs 3 within the frames and fastened thereto.The springs 3 may be fastened together and braced in any of a number ofwell known ways and those springs adjacent the frames 1 and 2 arefastened thereto by metal clips, or the like, such as 4:. Upholstery orseat covering material 5 is placed across and completely covers the topof the spring construction and depends down and covers the sides of theconstruction and extends a distance past the lower edges thereof. Theupholstery 5 thus completely covers the top and sides of the springconstruction.

.The above description, of the specific example illustrated, is typicalof the general type of spring seat construction, in which a series ofspiral springs are mounted in and fixed with respect to metal or thelike, frames at the opposite ends of the springs, and upholstery orcovering material is placed upon one of the frames covering the spaceacross said frame, depending across all of the sides, and fastened tothe opposite or bottom frame.

Various devices and arrangements have been used to fasten the dependingupholstery or covering to the lower frame, and my invention is directedparticularly to such a device,although of course, it is not limited touse upon the specific arrangement of spring construction disclosed butis applicable to a variety of such constructions.

The device of my invention comprises two members, the upholstery orcovering material receiving member A and the bind ing or locking memberB which is applied to the member A and binds or locks the upholstery orcovering material thereto and there in. The member A, in the particularexample illustrated, is in the form of a channel the means which fastenthe channel strip A to the frame of the spring construction by beingbent tightly therearound, as clearly shown in the accompanying drawings.

The binding or locking member B is formed of a strip orribbon of sheetmaterial in thickness less than the internal width of the space orchannel in the member A and approximately equal in width to the depth ofthe said space or channel. This locking member 13 is adapted to beforced into the channel strip for the purposes and in the mannerappearing hereinafter.

A spring seat being provided with the binding or locking member A intheform of a channel or U shaped member, fastened thereto by means ofthe tongues or clips 10 as explained, the operation and method by whichthe upholstery or seat covering mate rial is bound or locked therein andthereto and is maintained in position upon the spring seat, is asfollows:

The depending ends or edges of the upholstery or covering material 5 arecut off so that they extend or depend a distance be yond the lower oroutermost edge of the channel strip A. approximately a distance equal tothe depth of the channel or space in the strip. However, as shown in thedrawings, the depending ends of the material 5 may be of such length topermit curling over and depending a distance downwardly in the top ofthe strip A. The upholstery or covering material is then stretchedtightly on and over the spring construction and its free or dependingends forced or thrust into the channel or space in the channel strip A,formed between the sides 6 and 7, thereof. As soon as the endsof thematerial are in this position the binding or looking member B formed ofthe strip or ribbon of sheet material having been bent into theshape oroutline of the channel in the member A, is forced into this channel 9parallel to the ends of the material 5 therein and between these endsand the inner wall 6 of the channel strip. As pointed out the sides 6and 7 of the channel strip are resilient and as the thickness of thematerial and the binding or locking strip B together are greater thanthe width of the channel 9, the sides 6 and 7 will be forced outwardlybut will tend-to return to their normal positions, thus exerting apressure against the material and the strip therebetween and securelylocking them therein, and where the end of the material is curled overin the top of the channel strip the member B will bear thereagainst andsecurely hold the ends of the material 5 therein. This locking efiect isaided further and increased by the fact that the material 5 iscompressed, to a certain extent, by the action above pointed out andalso exerts pressure against the members between which it lies. In thismanner the upholstery or covering material 5 is firmly and securelymaintained in position upon the spring seat.

In Fig. 3, I have shown a modified construction of my invention in whichthe receiving member or channel strip A is formed with an interiorlongitudinal groove 11 in the side 7. In this arrangement the lockingstrip takes the form of a wire or rod as B which is adapted to be forcedinto the channel 9 between the sides 6 and 7 of the member A and to seatin the longitudinal groove 11. The ends of the covering material 5 areinserted in the channel strip A and the wire or rod locking member B isforced into the channel strip A, between the covering material 5 and theinner side 6 of the member A, until it seats in the groove 11. As thematerial 5 is between member B and groove 11, it is forced into thegroove by the wire or rod B and is locked or bound in and to thereceiving strip A. The spring or resiliency in the sides 6 and 7maintains the wire or rod B in the groove 11, thus securely locking theends of the covering material in the channel strip.

The binding or locking strips 13 or B may be readily removed from thechannel strip A to release the seat covering material ends therefrom.That is, my invention provides an arrangement whereby the upholstery orseat covering material may be fastened to a spring seat construction insuch a manner that it may be easily removed therefrom, and without inany manner mutilating or defacing the material.

A spring seat provided with the upholstery binding or locking means ofmy invention presents a finished, neat appearance, as the lower edges ofthe seat are covered by the material turned over the lower edge of theouter side 7 of the channel strip A, thus forming a smooth rounded edgeat the bottom of the seat, as shown in the drawings.

My invention may take other forms and constructions than the specificchannel strip and locking member of the drawings and other arrangementscan be provided for fastening the receiving member A to the lower frameof the spring construction without departing from the spirit and scopeof the invention. I also do not wish to limit my self to the particularlocation of the receiving member A upon the spring seat as it is obviousthat the same results and advantages would be secured at other points ona spring seat. My invention resides in the use of two members, oneadapted to receive the material and the other lock the same therein andthereto, the receiving member formed with means whereby it can besecurely and rigidly fastened to a spring seat, and the above resultsobtained without the use of the complicated and expensive arrangementsand constructions of the art.
